Dynamically set fieldinfos in popup template discussion

I want to create a certain function to streamline some of my customization work.

I work with a web app that's built using ArcGIS JavaScript API which contains a few layers.

Each layer is configured to an identity task that uses a popup template to display attribute information from the layer.

Now, there are lots of attributes PER layer that I manually configure up in the popup template declaration.

Ex.
    var popupContent = {
 title: "Business ID#: {UNIQUEID_1}",
 fieldInfos: [
 {fieldName: "BUSNAME_1", visible: true, label:"Business Name: "},
 {fieldName: "Standard_Name", visible: true, label:"Standard Name: "},
 {fieldName: "LATITUDE_1", visible: true, label:"Latitude: "},
 {fieldName: "LONGITUDE_1", visible: true, label:"Longitude: "},
 {fieldName: "INFO_EMP_1", visible: true, label:"Employment Info: "},
 {fieldName: "Est_Employment", visible: true, label:"Estimated Employment: "},
 {fieldName: "INFO_SAL_1", visible: true, label:"Salary Info: "},
 {fieldName: "Est_Revenue", visible: true, label:"Estimated Revenue: "},
 {fieldName: "PRMSIC4_1", visible: true, label:"Primary SIC: "},
 {fieldName: "NAICS_1", visible: true, label:"NAICS: "},
 {fieldName: "NAICS4_1", visible: true, label:"NAICS 4 Code: "},
 {fieldName: "NAICS4DESC_1", visible: true, label:"NAICS 4 Desc.: "},
 {fieldName: "NAICS2_1", visible: true, label:"NAICS 2 Code: "},
 {fieldName: "NAICS2DESC_1", visible: true, label:"NAICS 2 Desc.: "},
 {fieldName: "Use_Type", visible: true, label:"Use Type: "},
 {fieldName: "UseSubcategory", visible: true, label:"Use Subcategory: "},
 {fieldName: "UseCategory", visible: true, label:"Use Category: "}
 ]
    };

This is one of the shorter templates that i use, but as you can see, it gets pretty tedious to set these manually. Once in a while is okay, but the layers are constantly getting fields added/removed.

I was wondering if any of you had any clever ideas as to how I could automate this.

One possible way I was thinking is to have a table in my ArcGIS server that acts as a lookup table for the fields.
Table structure:

1. The column field names in this table will be the "Layername_fieldname" and "LayerName_label" of the layers in my web app (from the layers' corresponding attribute tables).

Ex.

    || Layer1_fieldname || Layer1_label || Layer2_fieldname || Layer2_label ||
    --------------------------------------------------------------------------
    || BusinessLoc      || Biz Location:|| CountyBoundary   || County Name: ||
    ||                  ||              ||                  ||              ||



2. Rows can be added or deleted as needed to each column as my web app layers grow or shrink in attribute size.

Basically, I want to know if this is a viable option or if there are other methods out there to perform this task. If this is a good solution, is it possible to query the field lookup table and use those values in my popup template constructor.

Any help or ideas would be greatly appreciated.

Thanks!
